, 'WIRE-DRAWING BENCH.

Application led April 8, 1925. lSerial No. 21,495.

The principal object of this invention is to provide a benclihaving a plurality of dies and drawing blocks for successively reducing or drawing down the w1re,`and hav- '10 ing means for automatically lubricating the wire as it entersy the dies and again while on the blocks. y

Another object Vis to provide an automatic lubricating systemfor wire drawinv benches, l which will vro'vide a continuous recirculation of the lubricating fluid. i

\ A further ob'ect is to provide a wire drawing bench having the novel construction, combination and design of parts hereinafter described and illustrated in the accompanying.y drawin In the drawings, tion of a wire drawing bench embodying my invention. p

Figure 2 is an enlarged fragmentary sectional elevation of the bench through a or- I tion of the trough and one of the die hol ers.

Figure 3 is an enlar ed transverse section on the line IV-IV of igiie'2v-g ings, the-letter A designated" the bench as a whole, which consists of the iisuallbase 2 and top 3. The working side ofithebench is provided with an overhangingtrough 4 adapted to contain lubricant. i t

The trough 4 is providedl with' a plurality of substantially equall spaced openings 5 through its bottom w. l and a plurality of hollow die holders 6 are secured to the bottom wall of the trough so that their hollow interiors aline with said o enings. The upper ends of said die hol ers are rovided with a die holding portion 7 adapte to hold a lie 8, and an inclined back wall 9 arranged' to the rear of the dies which is provi with outlet openings 10. The openings 10 are inclined toward the rearor enterin face of the die 8. A pair of side wings or anges 11 are provided at the upper end of the die holder and extend above the upper end of said back wall' 9, forming a recess or well.

` journaled in suitable bearings 14 on the top igure 1 is a' side eleva-V Referring more particularly'to'ltlie draw-v 3 of the bench A, and have their wire receiving portions or drum overhanging the trough 4. The drawing blocks 12 alternate with all of the die holders 6, with the eX- ception of the last or foremost die holder 6, so as to draw the wire through the dies 8. A verticaltakc-up block 12" is journaled in bearings 14a on bracket 15- at the forwardend of the bench to draw the wire through the foremost die 8 and form the drawn wire into a suitable bundle.

The drawing blocks 12 are each operatively connected to suitable independent motors 16 mounted on the top of the bench A, and the take-up block 12L operatively connected through gearing 17 and shaft 17 to a motor 16EL mounted on a bracket 16b extending out- 'wardlv from the forward end of the bench.

A suitable lubricant outlet conduit 18 eX- ytends forwardly from an outlet opening 19 A suitable lubricant supply conduit 22 extends longitudinally ofthe bench A under the trough 4 and isy connected toeachl of the hollowdie holders 6 by branches 23, which are provided with valves 24 for controlling tlie flow of lubricant into the die holders 6. y'

The conduit' 22 is connected by a branch 25 intermediate its ends to the outlet of a circulating pump 26 which has its inlet connected by a conduit 27 with the trough 4.

In operation, a quantity of lubricant is supplied-,in the trough 4 and the Aump 26 is operated to draw the lubricant rom the trough 4 and force it through the conduit 22 and branches 23 into the hollowdie holders 6, from which it is ejected through the outlet openings 10 and nozzle 20' so as to spray and contact with the entering side of the dies 8 and under side of the drawing blocks 12, thereby thoroughly lubricating the wire as it enters said dies and as it is wrapped vonthe blocks. The recess or well formed of the side. flangesv 11, causes the lubricant to flow back along the wire entering the v` dies 8 and thus further lubrieates the wire. Suitable horizontal drawing blocks 12 are The excess lubricant flows back intothe trough 4 and is constantly recirculated, thus secured thereon, a drawing block for pull-- ing the wire through said die, means for forcing lubricant up through said hollow die holder, and outlets from said die holder adapted to direct said lubricant upwardly against the entering side of said die and the face of saidblock. Y

2. The combination with a wire drawing bench, of a hollow die holder having a die secured thereon, a drawing block for pulling the wire through said die, an outlet opening in the upper end of said die holder, a conduit extending outwardly from the side of said die holder and terminating in a nozzle at a point beneath said block, extending under said die holder and block, means for forcing a How of lubricating liquid through saidhollow die holder so as to discharge through said outlet opening and conduitand Contact, respectively, with the entering face of' said die and the underside of said block, said lubricant being adapted to flow back into said trough, and means for recirculating said lubricant from said trough through said hollow die holder.

In testimony whereof, I have hereunto signed my name.
